Description

Cold suction energy storage device by using natural energy

The utility model relates to a kind of cold energy storage device of suction that utilizes natural energy, belongs to the energy saver technical field that adopts certain dynamoelectric equipment that the energy of the Nature is stored.

Northern China winter, temperature on average is usually about 0 ℃ or lower, many places are also keeping a kind of like this custom that stores natural energy so far: in severe cold winter, a thick layer of floating ice that freezes on the water surface in the ponds and pools of lake, river strike be cleaved into piece after, draw in hermetically storing in cellar or the cavern.Until during the warmth of spring, all the flowers bloom and hot summer, just gradually ice cube is taken out from freezing " logical sequence storehouse ", or ice drink, food in batches, be used for daily life; Or be used for the cooling of equipment, technology.On industrial and agricultural production and even health care, can both find this natural non-directly edible use occasion of freezing.This in the northern China severe cold cruel cold winter, the cold ┈ that obtains from the Nature is frozen, stored by certain means, to environment season change warm after, take out gradually again that to use be a kind of not catabiotic basically power-economizing method that utilizes the Nature difference variation and stored in batches.Because this method has remarkable energy saving effect, again surrounding environment is not had any pollution, so quite be subjected to northern various places people's welcome and glad the employing.

The purpose of this utility model provides another and utilizes the Nature temperature difference in season to obtain cold, and is stored, and takes out the cold energy storage device of suction that this cold uses again after the commentaries on classics of amblent air temperature condition is warmed up.

Device of the present utility model is equipped with as shown in Figure 1: the 1st, place outdoor glass steel cooling tower, its water inlet pipe 2 should with compressor, air-conditioner, the return pipe of transducing devices such as refrigerator is connected, device has the temperature sensor 4 of sensing water temperature in the cooling water pipe 3 in the cooling tower, the adaptation module 4A of these sensor 4 outputs and the contiguous inverter of laying 6, the adaptation module 6A of cooling tower fan electromotor 5,5A is plugged on 7 li in standard industry interface interface case, 7 in interface case is connected with microcomputer 8, and the outlet pipe 9 of cooling tower inserts in the water storage layer under the stratum by reversible floating well pump 10 backs.

Inverter 6 in the utility model can use the G5 series inverter of Japanese fuji company, standard industry interface interface case 7 can be selected the PB16AH or the PB16H type product of U.S. EPT22 series for use, or the product of OPT22 serial model No., microcomputer can be selected the PCU-1 type Industrial Control Computer of IBM PC or U.S. ME company (MECHATRONIC EQUIOMENT INC.) for use, and reversible floating well pump then can be selected the special-purpose series of products of the V2CP of electrical machinery general factory, domestic Tianjin for use.

The utility model also is to utilize northern China winter environment temperature lower, obtains cold from the Nature, by specific dynamoelectric equipment this cold is stored, and after amblent air temperature warms or when needing refrigeration, the cold that stores is taken out use again.Chiller of the present utility model mainly consumes natural energy, does not adopt traditional refrigeration method to obtain cold, so do not consume energy basically.In fact, it is a kind of energy saver that stores natural energy.Its operation principle is: from air-conditioner, the water inlet pipe 2 hub disk eddy flows that the hot water that transducing devices return pipes such as compressor flow out flows to cooling tower 1 move, outdoor cooling tower fully absorbs the cold air of atmospheric environment, make the water heat release of 3 li of its cooling water pipes inhale cold rapid cooling, because of be placed with the temperature sensor 4 of sensing water temperature in 3 li in water pipe, the adaptation module 4A of its output is inserted in 7 li in industrial interface case, and be connected with computer 8, can carry out Treatment Analysis to the water temperature data by giving the program software of setting earlier, and then send control instruction, transmission by adaptation module in the interface interface case, change the main frequency of DWM type inverter 6, thereby the rotating speed of the cooling tower fan electromotor 5 that is subjected to its power supply is changed thereupon, like this, also just controlled the exhaust air rate of cooling fan 5, the water temperature that flows out cooling tower is controlled in 0.2～2 ℃ of scope.This water temperature is 0.2～2 ℃ the cold water water storage layer under reversible floating well pump 10 is injected into stratum bottom again.Through the working cycles of certain hour, the bottom water temperature of reservoir bed just can be steady in a long-term between 2～4 ℃.Because the heat transfer situation below the stratum is very poor, the cold water capacity of storage is very big again, so just is equivalent to set up a natural refrigerator underground.During refrigeration, as long as open reversible floating well pump, make it reverse running if desired, just can take out the cold water that stores, the transducer of flowing through again puts that enfleurage is hot just to be used.

The low-temperature receiver grade that the utility model device produces is not high; the most suitable as the low-temperature receiver that room air conditioner is used; can directly adopt preparation, storage and the feedway of the utility model as the refrigeration filling in the house central air-conditioning system; the refrigeration filling that utilizes the utility model device to store cold is a water; pollution-free, low noise; compare with conventional air-conditioning equipment; biggest advantage be need not be traditional cold-producing medium ┈ fluorine Lyons or lithium bromide, thereby can protect environment to make the ozone layer in the atmosphere exempt from infringement.Also can make the central air conditioning working media, reduce equipment investment and power consumption because of the cold water that adopts natural cold-amount.The underground cold water of this employing is done the tentative enforcement of air-conditioning medium, obtains checking at buildings such as China Hangzhou new city restaurants, and it is over half to save equipment investment, and economize on electricity reaches 80%.

This low-grade low-temperature receiver of the utility model also can be used as the energy-saving appliance low-temperature receiver of industrial refrigerators such as refrigeration, oil gas processing, chemical industry, electronics.So also effective energy savings.With 600,000 kilocalories/hour the ammonia refrigerator group be example, be-30 ℃ as evaporating temperature, condensation temperature is 30 ℃, its consumed power is about 180 kilowatts.If before entering compressor, earlier medium is reduced to 10 ℃,, wherein directly provides cold energy-conservation about 30% by energy-saving appliance as long as the wasted work less than just can reach identical cooling effect for 100 kilowatts with energy-saving appliance, by reducing energy-conservation about 30%, two addition of compressor load energy efficient nearly 60% altogether.And if environment temperature is high more, then energy-saving effect is remarkable more.
